How theaviansh-dev/express-typescript works

This is a sample Express/TypeScript backend. Requests pass through app middleware to the root handler or mounted API routes; API handlers list MongoDB collections or accept uploaded files. Startup connects the database and mounts routes before listening, while shutdown closes the database and listener. The README also advertises Zod validation, but no validation implementation appears in the supplied tree or excerpts, so it is not mapped.
